[vtkusers] Best way to add a print in a distribution file ?

[kenichiro yoshimi]

Hi,

Probably, you are calling a function defined by
  vtkGetVectorMacro(Point1,double,3);
and hence a function to which you have added print
 void vtkLineSource::SetPoint1(float point1f[3])
may not be called.

Regards,
